COAL-OIL STOVE.

SPECIFICATION forming part of Letters Patent No. 230,850, dated August10, 1880.

Application filed J une 25, 1877.

To all whom it may concern Be it known that I, J. MoGREeoR ADAMS, ofChicago, in the county of Cook and State of Illinois, have inventedcertain new and useful Improvements in Goal-Oil Stoves; and I do herebydeclare the following to be a full, clear, and exact descriptionthereof, which will enable others skilled in the art to which myinvention appertains to make and use the same, reference being had tothe accompanying drawings, forming part of this specification, in whichFigure 1 represents a vertical longitudinal central section of acoal-oil stove embracing my said invention. Fig. 2 represents a verticaltransverse central section of the same.

My invention relates to that class of coaloil stoves designed moreespecially for the purpose of cooking; and the object of my invention isto improve the construction of such stoves, so as to render them moreconvenient in use and more perfect in operation, and to prevent themfrom being exploded by the formation of explosive gases within theoilreservoir.

The invention consists in the special construction and arrangement ofthe oil-reservoir and wick-receptacles, and also in a special device forthe protection of the filling-aperture to prevent explosions.

In the drawings, A represents the oil-reservoir, which may be cast ofany suitable metal and in any desired form, but is made entirethat is,the top and sidesare cast in one piece and the bottom soldered theretoafter the wick-receptacles are in place, so that the completed base iswithout openings except an aperture in the'top, through which thereservoir may be filled, and one or more slots, at, in the top, in whichthe wick-tubes are inserted.

The wick-tubes O are of ordinary constructlon, and at their lower endsare inserted in the slots a, within which they are secured, and thuscommunicate directly with the interior of the reservoir, and are alsoprovided with ordinary ratchetshafts D. Upon this reservoir as a basemay be placed a superstructure of varied construction for the purpose ofcompleting the stove. One is shown in the drawings, in which there arecolumns E rising from the reservoir, on which is supported awater-reservoir, F, leaving an ,airspace, G, between it and theoil-reservoir.

The bottom of the water-reservoir is raised in the center, so that, inconnection with a perforated diaphragm, H, immediately below, anair-chamber, d, is formed around the wicktubes. The diaphragm H issupported by ribs 0 on the wick-tubes.

The usual deflecting-cones J are arranged above the diaphragm around theupper ends of the wick-tubes and extend upward through thewater-chamber.

M M are the chimneys. -A sheet metal jacket or drum, K, is mounted upona plate, k, over the water-reservoir, and is held in place by a metalcap, L, and screw-bolt N, the construction being an ordinary one, andnot requiring special description here.

A small receptacle, m, of perforated metal plate or wire-gauze, isattached to the under side of the top of the oil-reservoir, immediatelyunderneath each slot for the wick-tubes, and depends from thereservoir-top within the reservoir itself. These receptacles are for thepurpose of retaining each wick independently of the others and of thereservoir itself, and at the same time permitting the oil to pass freelywithin them to saturate the wicks, the walls of the receptacles beingperforated sufficiently fine to prevent the flame from passing throughthem should the oil and vapor within the receptacles be ignited, therebypreventing an explosion of the oil in the reservoir.

The filling-aperture B in the top of the oilreservoir is provided with atubular stopper, B, which has a diaphragm, a, of perforated plate orwire-gauze, which permits the escape of gases generated within thereservoir, but at the same time is a preventive of explosions resultingfrom external causes.

The fillingaperture B may also be provided with an interior safety-tube,h, closed at its lower end. This tube is also made of wiregauze orperforated plate, and the tubular stopper fits within it, so that itserves as an additional device to prevent explosions, while at the sametime the oil will pass through it readily to fill the reservoir.

The peculiar construction and arrangement of the oil-reservoir andwick-receptacles above described are very cheap and simple, and providea substantially closed top for the oil-reservoir, there being no looseand removable pieces except at the filling-aperture; but thisfilling-aperture, as will be readily understood from the abovedescription, is thoroughly protected, so that explosions resulting fromthe ignition of the oil within the reservoir are almost, if not wholly,impossible.

Having; thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is is 1. A closed oil-receptacle, A, the topof which is entire, except a filling-aperture and a slot or slots withinwhich the wick-tubes are secured, in combination with the \ricktubes O,
